I make sure everything is sealed with a good urethane sealer. If it's a stained wood, what you see it usually sealed but everything else that is not sealed I coat with Valspar. I give everything "raw" a good couple of coats. Wood, MDF, pressed board, whatever... Once everything is seal up, I mix 50/50 white vinegar and RODI water and just spray/wipe.
I've seen a few nice cabinets rot from the inside because nothing was sealed up. The stained and sealed wood on the outside looked great but everything on the interior had been exposed to high humidity and saltwater for years and years.
